Step 1: Get the delta firmware package from Quectel.
Step 2: Put the delta firmware on HTTP(S) server.
Step 3: Execute AT+QFOTADL command. Then the module will automatically download the package
from HTTP(S) server via LTE/GPRS network (Step 4) and finally automatically upgrade the
module’s firmware (Step 5).
2.1. Get Delta Firmware Package
Before upgrading, customers need to check the current firmware version (the old version) by executing
ATI command, and also need to know the target firmware version (the new version). Then the two
firmware versions should be provided for Quectel or the module supplier, to get the delta firmware
package.
2.2. Put Delta Package on HTTP(S) Server
When using the DFOTA function, customers need to setup an HTTP(S) server by themselves, for Quectel
does not provide such a server. Then please put the delta firmware package on the server, and record the
HTTP(S) path. The module will get the delta package from the path after executing corresponding AT
command.
2.3. Check APN Setting
After putting the delta firmware package on the HTTP(S) server, there is a need to check whether the APN
is set properly. For instance, the APN for Telstra (U)SIM card should be “Telstra.internet”, and the
relevant AT commands are listed below:
 Query APN: AT+CGDCONT?
 Set APN: AT+CGDCONT=1,"IP","Telstra.internet"
For more details about AT+CGDCONT, please refer to Quectel_BG96_AT_Commands_Manual.
